Though recent suicide bombings in Volgograd may be an attempt to create fear in the run-up to the Sochi Olympics next month, anyone planning to visit Russia for the games should take precautions, Howard Hall, the UT-ORNL Governor’s Chair for nuclear security, told the Knoxville News Sentinel. “You can interpret these early events as them trying to set the stage to where they control the narrative of fear in the beginning rather than having an event at the Olympics itself, though we can’t say for certain (an attack won’t happen),” he said.
